Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

UTMD, QXIH, MBEL, IFAP, ?

EJWT

Explanation:

UTMD, QXIH, MBEL, IFAP, ?

The logic followed here is :

U → (-4) → Q → (-4) → M → (-4) → I → (-4) → E

T → (+4) → X → (+4) → B → (+4) → F → (+4) → J 

M → (-4) → I → (-4) → E → (-4) → A → (-4) → W

D → (+4) → H → (+4) → L → (+4) → P → (+4) → T

So, the letter-cluster that replaces the (?) to complete the series is "EJWT'
